ABSTRACT:
A conveyor assembly with uniformly spaced-apart grippers for sheet-like printed products wherein the grippers are pulled along a plastic guide by one or more endless flexible bands which replace conventional chains. Each gripper has one, two or more roller followers which are movable along one, two or more tracks defined by the guide. The guide has one or more plastic rails which are affixed to a strip-shaped metallic carrier. The grippers have pairs of jaws one of which supports the follower or followers and the other of which is pivotably mounted on the one jaw and is permanently biased to an operative positioned or to an inoperative position by a prestressed leaf spring which is integral with the second jaw.
